I think it would ease the understanding of broker authentication if there were some examples of the Uris. I am still struggling with their meanings. When I understand it correctly the ProfileUri should be either "http://opcfoundation.org/UA-Profile/Security/UserToken/Client/UserNamePassword" or "http://opcfoundation.org/UA-Profile/Security/UserToken/Server/UserNamePassword" for username/password. And the ResourceUri could be the Url of the broker? Maybe with a username part (e.g. "mqtt://username@computername:1883") ? |
